Walmart is up to it’s Roll Back tricks again and has announced that they will be carrying the new iPad Air on November 1st at the discounted price of $479 for the 16GB WiFi model. That is $20 below the retail price of $499, the biggest such discount we’ve ever seen at launch. There is no word if this discount will be extended to other iPad Air models or the new iPad mini with Retina display when it is released later in November.
